Non bristle swimming pool and spa brush

ABSTRACT

The present invention provides an improved non-bristled brush for cleaning underwater surfaces, such as swimming pool walls and bottoms, and uses a sponge like cushion that is wrapped in absorbent material which can loosen dirt, algae and leaf stains.

FIELD OF THE INVENTION

The present invention relates to a non bristled brush used in cleaning swimming pools and spas,

BACKGROUND OF THE INVENTION

Through our experience of having an in-ground vinyl liner pool and having experienced the use of bristled swimming pool brushes that a new and improved means of cleaning the bottom came to light. Initially we wrapped a towel around an existing pool brush and tied it securely around the bristled pool brush. We found that it became easier to remove algae and leaf stains at the bottom of our vinyl liner pool with the toweling material. One problem we continued to experience was the deterioration of the bristles of the bristled pool brush caused by the chlorine and sunlight through normal use. The sharp bristles were everywhere. So the innovation of the Pool Swipe Pro came about. But what about others who came before?

SUMMARY OF THE INVENTION

If one could get years of additional service from their pool by using a non-bristled non-destructive pool brush, the owner would benefit economically from the improvement. Likewise, if the painted surface of a concrete pool could last for additional years before re-painting because of the use of a non-bristled brush, then it too would be considered a money saving device. Through these needs came this development and improvement to bristled pool brushes. It is now easier to loosen dirt and algae from the bottom and wall surfaces due to the added weight of the brush instead of trying to gouge our the debris from the surface as in the use of bristled pool brushes. One will instantly recognize the advantage of non-bristled pool brushes and the economic advantage it has for the consumer.

Swimming pool brushes have been around for many years as long as swimming pools. Most traditional swimming pool brushes have an elongated handle receiver connected to a brush head. See for example U.S. Pat. No. D. 351,948 to Getchell; U.S. Pat. No. 3,296,643 to Fortune; U.S. Pat. No. 4,637,087 to Feinberg; U.S. Pat. No. 4,703,535 to Nehls; U.S. Pat. No. 4,733,427 to Conrad; U.S. Pat. No. 4,783,868 to O'Callaghan; and U.S. Pat. No. 5,487,397 to Bean. However, these references are limited to having bristles

U.S. Pat. No. Des. 257,521 to Piero; and U.S. Pat. No. 4,176,419 to MacDonald each describe other pool brushes where the bristles are only oriented about part of the perimeter edges of the brush head, and are also not capable of adequately cleaning all corners where walls and floors come together, areas where different planar walls intersect, edge areas where walls meet floors, around stairs, seats and the like.

U.S. Pat. No. 2,083,134 to Wood shows a complex brush for “cleaning vats” having separately positioned bristle heads attached to two parallel brush heads, and also would not appear to be capable of adequately cleaning all corners where walls and floors come together, areas where different planar walls intersect, edge areas where walls meet floors, around stairs, seats and the like.

U.S. Pat. No. 3,273,187 to Williams shows a triangular “vacuum cleaner head” of bristles that would be difficult to maneuver and use for adequately cleaning all corners where walls and floors come together, areas where different planar walls intersect, edge areas where walls meet floors, around stairs, seats and the like.

U.S. Pat. No. 4,479,277 to Gilman et al. describes a scrub pad brush with downwardly oriented bristles and one side edge having rounded edge bristles.

U.S. Pat. No. 6,148,466 to Smitelli, III et al. discloses a pool brush having a cylindrical body with semi-spherical rounded ends. The bristles, when the head is seen in cross section, extend about 280 degrees around the body with the body having a flat portion in top.
